CD4040BE Ripple-Carry Binary Counter Divider IC

The CD4040BE Ripple-Carry Binary Counter is a 12-bit binary counter/divider from the CMOS 4000 series. It operates on a wide supply voltage range (3V–15V), making it compatible with a variety of digital and timing circuits.

Each incoming clock pulse advances the binary count by one, with outputs available for each stage. This allows division of clock frequencies by 2, 4, 8, … up to 4096. The CD4040BE is commonly used in timing systems, digital clocks, frequency dividers, and control applications.

It features low power consumption, high noise immunity, and TTL compatibility, making it reliable for both hobbyist and industrial projects.
